IMPROVEMENT IN PLOW'S.

To all whom it may concern:

Be it known that we, N. S. LOGKWOOD and J. D. WINN, of Dayton, in thecounty of Mont gomery and State of Ohio, have invented a new and usefulImprovementin the Construction of Plows; and we do hereby declare thatthe following is a full, clear, and exact description of the same,reference being had tO the annexed drawings, making apartof thisspecification, in which'- Figure l is a side view of the mold-board'Iside of the metal portion of the plow. Fig. 2

is a side view ot' the Opposite or land side et' the same. Fig. 3 is aback view of the same. Fig. 4 is a side view Or" the land side of thesame. showing a breast attached to the moldboard and share instead of apost, as shown in Figs. 1, 2, and 3.

The nature Ol' our invention consists in a peculiar mode Ot'attachingthe post or breast to the mold-board, and in the peculiar modeof attaching the share to the mold-board, as will be presently shown anddescribed.

To enable those skilled in the art to fully understand and construct ourinvention, we will proceed to describe it.

A, Figs. 1, 2, and 3, represents a cast-iron upright, commonly termedthe post,77 the upper part ot' which is jirmly attached in the usualmanner to the beam of the plow. B is themold-board,constructedol'cast-steel. rlhe post A is Welded to thefrontend of the moldboard, the dotted lines D in Figs. l and 2 showingthe points of contact. The lower end of the post A has a horizontalliange, A', cast with it, said ange being welded to the inner side ofthe mold-board, as shown at E, Figs. 2, 3, and 4.

C represents the share, and C is the landside, which are cast in onepiece. The front ends ot' the share and landside are connected byahorizontal plate, O, on which the lower end of the post A and flange Arest. FFare screw-bolts, which pass through the ange A and plate O andfirmly secure the mold-board and post to the share and landside.

By the above improvement in the construction of plows no bolt-heads areexposed on the outer sideof the mold-board or share, and the mold-boardmay be hardened or properly tempered so that it will retain its originalshape.

In case wooden posts are used, a breast, A", may be welded to themold-board B, as shown in Fig. 4, and the lower end ot the wooden postattached to the breast bya screw-bolt, H. The

only difference between the breast A and the post A is that the postisconsiderably higher than the breast, both being attached to themold-board in the same manner.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

Weldingthe post A Or breastA" to the m'oldboard B and attaching theshare O and landside C to the mold-board and post or breast by meansofthe flange A at the lower end ot' the post or breast and the plate Cof the share and landside, through which flange andk plate screw-bolts FF pass, substantially as shown, for the purpose specified.
